1. Omega-3 Fatty Acids (Should)

Omega-3s are great for your pet’s skin, coat, and overall joint health. They help reduce inflammation and support a shiny coat, especially for pets with skin allergies or arthritis. Always choose high-quality fish oil or krill oil supplements.
2. Glucosamine and Chondroitin (Should)

These joint supplements can be beneficial for older pets or those with arthritis, as they help protect cartilage and improve joint function. They’re commonly used for dogs, but they can be helpful for cats too, particularly in easing mobility issues.
3. Probiotics (Should)

Probiotics can improve your pet’s digestion by balancing the gut flora. They’re especially useful after antibiotic treatments or for pets with chronic digestive issues, like diarrhea or gas. Choose pet-specific probiotic blends for the best results.
4. Multivitamins (Shouldn’t, Unless Advised)

While multivitamins may seem like a good idea, most pets on a balanced diet don’t need them. Over-supplementing can actually do more harm than good, so only give multivitamins if advised by your vet for specific nutritional deficiencies.
5. CBD Oil (Should)

CBD oil has grown in popularity for its calming effects and potential to reduce pain and inflammation. It’s used to treat anxiety, arthritis, and even seizures in some pets. Always consult with your vet to ensure the proper dosage and safety for your pet.
6. Calcium Supplements (Shouldn’t, Unless Prescribed)

Calcium is important, but too much can lead to problems like kidney stones or skeletal issues. Pets on a well-balanced diet, especially those on commercial pet food, typically get enough calcium. Only supplement if prescribed by a vet for specific conditions.
7. Vitamin D Supplements (Shouldn’t)

Vitamin D toxicity is a real concern in pets. Most commercial pet foods contain the right amount of vitamin D, so supplementing without a vet’s supervision can lead to dangerously high levels, affecting your pet’s bones and kidneys.
8. Milk Thistle (Should)

Milk thistle is a natural supplement that supports liver health and helps detoxify the liver. It’s especially useful for pets on medications that can be hard on the liver or pets with liver disease.
9. Digestive Enzymes (Should)

For pets with sensitive stomachs or difficulty digesting certain foods, digestive enzymes can help break down proteins, fats, and carbohydrates. This ensures they’re getting the most nutrients out of their food and can reduce symptoms like bloating or gas.
10. Garlic (Shouldn’t)

Though sometimes touted as a natural remedy, garlic can be toxic to dogs and cats, causing gastrointestinal upset and even damage to red blood cells. Avoid any supplements or foods that contain garlic.
11. Antioxidants (Should)

Supplements like Vitamin E, Vitamin C, and selenium can support your pet’s immune system and help fight off free radicals, which can damage cells and accelerate aging. Antioxidants are especially helpful for older pets or pets with chronic health conditions.
12. Iron Supplements (Shouldn’t, Unless Necessary)

Too much iron can be harmful to pets, leading to issues like vomiting, diarrhea, or even organ failure. Only use iron supplements if your vet has diagnosed anemia or an iron deficiency in your pet.
13. Biotin (Should)

Biotin is a B-vitamin that supports skin, coat, and nail health. Pets with dry skin, brittle nails, or thinning fur can benefit from biotin supplements, particularly in breeds prone to skin issues.
14. Turmeric (Should)

Turmeric is a natural anti-inflammatory supplement that can help alleviate joint pain and stiffness, particularly in aging pets. It’s known for its ability to reduce inflammation and support overall joint health when given in the correct doses.
